Self-reported sleep complaints are common in peri- and postmenopausal women and have been identified as a key symptom of the menopausal transition. The MsFLASH study, A Pilot Trial of Telephone-Based Cognitive-Behavioral Therapy for Midlife Women with Menopause-related Sleep Disturbance, is a randomized, single-blind, placebo-controlled, two arm clinical trial. The target population will include women in general good health, aged 40-65 years, who report symptoms of insomnia (trouble sleeping) and who are bothered by hot flashes. We plan to enroll 100 women from Seattle, Washington and surrounding areas into the trial. Half of the women will be randomly assigned to receive the behavioral intervention and half to receive the behavioral control.
